The sprints are progressive. The first sprint begins at a jog and climaxes at 50% of maximum effort; the second sprint goes from 40% at the beginning to 60% at the climax; the third sprint goes from 50-70%; the fourth sprint from 60-80%; the fifth sprint from 70-90%; the sixth sprint reaches 95% of maximum effort; the seventh and eighth sprints are run at 95-100% effort.

If you are not accustomed to the type of sprint training we do around here, do not max out on the final three sprints - climax between 80-90% of maximum effort.
